DISINFECTING DEVICE.

Specification of Letters Iatent.

Patented July 4, 1911.

Application filed October 4, 1910. Serial No. 585,216.

To all whom it may concern:

Be it known that I, THADH. ROWLAND, a citizen of the United States,resident of Oberlin, county of Lorain, and State of Ohio, have inventeda new and useful Improvement in Disinfecting Devices, of which thefollowing is a specification, the principle of the invention beingherein explained and the best mode in which I have contemplated applyingthat principle, so as to distinguish it from other inventions.

This invention relates broadly to a disinfecting device, and morespecifically to such as are adapted for the purification of gases.

The object is the provision of an efiicient construction which, byreason of its simple theoretical application, shall be economical ofmanufacture.

The said invention consists of means which are hereinafter fullydescribed and particularly set forth in the claims.

The annexed drawing and the following description set forth in detailcertain means for carrying out my invention, the disclosed means,however, constituting but one of various mechanical forms in which theprinciple of my invention may be applied.

In said annexed drawing :the figure is a vertical cross-section of mydevice.

The structure comprises a closed receptacle A with a hermeically sealedinlet pas sage (6 below, and a similar hermetically sealed outletpassage a above. The upper and lower portions of the receptacle properare preferably tapered, as shown at (0 Interiorly, the receptacle isprovided with a series of brackets 13, which shall serve, as clearlyappearing in the drawing, as a supporting bracket for a tank C. Thistank is somewhat smaller in diameter than the receptacle, so as to leavean annular space surrounding it. It will now be apparent that any gaseswhich it is desired to purify may readily pass up through the spiderinto the space surrounding the tank.

The tank C may be supplied with any disinfectant, such as a solution offormaldehyde, in any suitable manner, as by the pipe D, valve 65 andfunnel cl, as will be readily understood. The tank is further open atthe top, and spaced some distance from the upper tapered portion of thereceptacle, in order that the incoming gases may freely co-mingle atthis point with the rising disinfecting fumes, and thereafter pass intothe outlet opening.

It will be noted that the device, while exceedingly simple, neverthelessembodies a positive disinfecting means.

Having fully described my invention, what I claim and desire to. secureby Letters Patent is 1. In a disinfecting device, the combination of anouter receptacle provided with a downwardly tapered bottom having aninlet passage therein and an upwardly tapering top provided with anoutlet passage, an inner receptacle for holding disinfecting substancessupported by and spaced laterally from the sides of said outerreceptacle, said receptacle also being spaced from the tapered top andbottom of said outer receptacle and provided with an unobstructed opentop, a pipe passing through the wall of said outer receptacle andcommunicating with the interior of said inner receptacle and a valvecontrolling the passage in said pipe.

2. In a disinfecting device, the combination with an outer receptaclehaving a clownwardly tapering bottom terminating in an inlet passage andan upwardly tapering top terminating in an out-let passage, a series ofbrackets secured to the wall of said receptacle, a receptacle forcontaining disinfectant supported by said brackets midway between theinlet and outlet passages and spaced therefrom and laterally from thesides of the outer receptacle, said inner receptacle being provided withan unobstructed open top, a pipe communicating with the inner receptacleand passing through the wall of the outer receptacle and a valve forcontrolling the passage through said pipe.

Signed by me, this 16th day of Sept,

THAD H. ROWLAND. Attested by CURT B. MUELLER, *WINIIPRED WALTZ.
